How do I set up an Express server with MongoDB?

To set up an Express server with MongoDB, you'll need to install Node.js, Express, and the MongoDB driver. Would you like a step-by-step guide?

Yes, please provide the steps.

First, create a new directory for your project and run npm init -y to initialize it. Then, install Express and MongoDB using npm install express mongodb.

What should I do after installing those packages?

Next, create a file named server.js. In this file, require Express and MongoDB, set up your Express app, and connect to your MongoDB database.

Can you show me a sample code for that?

Sure! Here's a basic example:

const express = require('express');
const { MongoClient } = require('mongodb');

const app = express();
const url = 'your_mongodb_connection_string';

MongoClient.connect(url, { useNewUrlParser: true, useUnifiedTopology: true })
  .then(client => {
    console.log('Connected to Database');
    const db = client.db('your_database_name');
    // Your routes go here
  })
  .catch(error => console.error(error));

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

Replace your_mongodb_connection_string and your_database_name with your actual details.
